Multimodal Neuroimaging of Intimal Flap in a Basilar Artery Dissection

Spontaneous dissections of intracranial arteries are rare diseases with a poor prognosis and a frequent hemorrhagic presentation. This digital subtraction angiography demonstrates spontaneous basilar artery dissection in a patient presenting with ischemic stroke involving two-thirds of the vessel course and with the main vessels originating from the false lumen. The main hallmark of dissection, ie, the intimal flap, is also well evident. Click the Related Article link for full details.
